NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the

mass, balance, structural strength, reliability, operational characteristics affecting the

airworthiness of the product. All other changes are major changes.

REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

During the AIRBUS production flight test of an A330-300 aircraft, the Ram Air Turbine (RAT) did not

pressurize the green hydraulic system. Investigation revealed that the impeller drive (hex) shaft had a

reduced length of engagement with the pump drive shaft. This caused the impeller drive shaft to

disengage from the pump and disconnect the impeller. It was determined that the root cause of the

disconnection was the internal hex dimensions on the pump impeller shaft had been changed in a

supplier drawing in October 2007.

This Service Bulletin is published to advise all operators of A340-200/300 aircraft of the issue of

HAMILTON SUNDSTRAND Service Bulletin ERPS06M-29-19. This introduces an inspection to the RAT

hydraulic pump via serial numbers to ensure that all suspect RAT hydraulic pumps are captured. If the

RAT pump is suspected, It also outlines the modification to the RAT hydraulic pump by the installation

of a new hex drive shaft with an increased hex socket length and an increased internal hex depth.

This Service Bulletin installs a new impeller drive shaft that is match sized in the retrofit process of the

pump to ensure a minimum engagement of the hex drive shaft to eliminate the possibility of impeller

disengagement. The incorporation of this modification will provide improved reliability of the RAT.

SERVICE BULLETIN

(2) Objective/Action

This Service Bulletin is published to advise all operators of A340-200/300 aircraft of the

issue of HAMILTON SUNDSTRAND Service Bulletin ERPS06M-29-19. This introduces

an inspection to the RAT hydraulic pump via serial numbers to ensure that all suspect

RAT hydraulic pumps are captured. If the RAT pump is suspected, It also outlines the

modification to the RAT hydraulic pump by the installation of a new hex drive shaft with

an increased hex socket length and an increased internal hex depth.

(3) Advantages

This Service Bulletin installs a new impeller drive shaft that is match sized in the retrofit

process of the pump to ensure a minimum engagement of the hex drive shaft to

eliminate the possibility of impeller disengagement. The incorporation of this modification

will provide improved reliability of the RAT.

(4) Operational/Maintenance Consequences

None

D. DESCRIPTION

To accomplish this Service Bulletin it is necessary to :

Task 294093-831-848-001: Modification

(1) Re-identify the RAT Hydraulic Pump

(2) Replace the RAT Hydraulic pump

(3) Re-identify the RAT Module

E. COMPLIANCE

(1) Classification

MANDATORY: Service Bulletin must be accomplished.

(2) Accomplishment Timescale

This modification must be embodied within 36 months from the Airworthiness Directive

(AD) effective date. An AD will be issued to mandate the necessary changes.

This Service Bulletin has been classified Mandatory. It is expected that an Airworthiness

Directive (AD) published by the European Aviation Safety Agency (EASA) will be issued

to confirm this classification. It is anticipated that the AD will confirm the (thresholds

and/or intervals and/or date) given above but reference should be made to the AD for

confirmation of the mandated accomplishment timescale.

F. APPROVAL

The technical content of this document is approved under the authority of Design

Organisation Approval No. EASA.21J.031.

SERVICE BULLETIN

If an aircraft listed in the effectivity has a modification or repair embodied that is not of

AIRBUS origin, and which affects the content of this Service Bulletin, the operator is

responsible for obtaining approval by its airworthiness authority for any adaptation necessary

before incorporation of the Service Bulletin.

G. MANPOWER

The manpower estimates given in this Service Bulletin are based on the direct labor cost to

do the work. These estimates assume that the work will be done by experienced personnel,

and may need to be revised upwards to suit operator’s circumstances. The estimates do not

include the time to prepare, plan or inspect the work. Manufacture and procurement of parts

and tools, drying times for paints, sealants, etc., and general administration work are also not

included.
